MOLYKOTE D-321 R Anti-Friction Coating Spray

Overview

MOLYKOTE D-321 R Anti-Friction Coating Spray is an air-curing dry-film lubricant in aerosol form, filled with the solid lubricants molybdenum disulfide and graphite. It is designed for metal/metal combinations with slow to medium-fast movements and high loads, and is used to improve the running-in process and for lubricating plain bearings, bushings, sleeves, power screw drives, threaded connections and high-voltage switches, even under high vacuum and at extreme temperatures. The spray is frequently used on hard-to-reach surfaces, for emergency boundary lubrication and on chains. It avoids stick-slip, has high ageing resistance and contains no intentional PTFE or PFAS.
